sn754410 or L293D

[Zulander]

I don't know which IC to pick between sn754410 or L293D; I need a Half-
Bridge Driver for my stepper because it's a bipolar. Those IC's are
both made by Texas Instrument. There is a huge price difference
(digikey) and they are almost the same, I can't seem to identify the
difference expect that the L293D have an internal diodes and the
sn754410 doesn't. And I looked on line for difference and I couldn't
find any proper explanation



sn754410 (http://focus.ti.com/lit/ds/symlink/sn754410.pdf)

Price: 1.88 $ / unit



L293D(http://focus.ti.com/lit/ds/symlink/l293d.pdf)

Price: 4.32 / unit



So which one do you think I should go for? I was going for the L293D
but now I am not sure anymore because I need 3 of those!

Thanks you
